I want to text him-please talk me out of it

I want to know if he is seeing someone. We talked a few days ago and he said he is just taking time for himself. He hasn't gotten with anyone or slept with anyone. We have been broken up for 2 months and I know I shouldn't care but I can't help it. We were together 6 years and engaged for 2.  I am trying to talk myself out of texting him and just believe he is taking time for himself. I keep snooping (yes I need to stop) but my name is still on his one bank account so I looked and he spent $72 at a wine and liquor store. He could be going to a a party this weekend, be buying wine for himself (he went through a wine phase when we were together) or God knows what else. After we broke up he was drinking red bull and vodka (which isn't like him) so maybe he is just drinking again.  But in my crazy mind I think he had a girl over for dinner. Help ladies, I'm going crazy!
